MehaAI Trading Advisor

MehaAI Trading Advisor
A smart trading advisor for MT5 that combines technical data analysis and real-time news through OpenAI.
It automatically generates buy / sell / hold signals with SL/TP levels, takes into account risk, broker restrictions, and account status, and then opens and manages trades on its own.

What the advisor does

• Analyzes the market on timeframes from M1 to MN1.

• Calculates indicators: RSI, SMA(50/200), ATR, volatility, volumes, H1 support/resistance levels.

• Considers news context: economy, politics, analysts’ opinions (OpenAI + web search).

• Returns a structured response with action (buy/sell/hold), SL, TP, and reasoning.

• Trades fully automatically: position opening/maintenance, SL/TP placement, lot calculation based on MaxRisk.

OpenAI effectiveness in trading

Using OpenAI gives the advisor an edge over classical algorithms:

• News factor – AI can analyze current events (economy, politics, markets) and integrate them into signal formation, unlike standard indicator-based systems.

• Adaptability – the model adjusts logic to changing market conditions instead of working on rigid rules.

• Contextual thinking – unlike simple strategies, OpenAI evaluates the market comprehensively: technical indicators + fundamental news + risk constraints.

• Reduced false signals – AI can “hold” if a setup is weak or violates risk rules, which reduces losing trades.

• Improved entries – even with the same risk management strategy, OpenAI-generated signals provide more balanced SL/TP levels, accounting for volatility and market background.

⚠️ However, it’s important to understand:
AI does not guarantee profit and does not predict the future — it only improves the quality of analysis.
Final effectiveness depends on risk settings and the chosen model (gpt-5 or gpt-5-mini).

Key features

• Integration with OpenAI and web search — real-time news and analytics.

• Risk management — lot size is calculated from MaxRisk (balance share per trade); considers StopsLevel, FreezeLevel, lot step, margin.

• Netting and hedging — bulk SL/TP setup for all positions on an instrument.

• StrictDirection — on direction change, the advisor does not open counter trades to “net out”; it first reduces volume on the current side (reduce), and only if needed adds missing exposure in the signal direction (add).

• Accurate net exposure logs — records NET BUY/SELL X.XX across N positions.

• Safe levels — SL/TP set with ATR buffer and broker restrictions in mind (SafeMinDist).

• Smart order execution:

  • Iteration over filling modes (IOC/FOK/RETURN),

  • Volume reduction on errors,

  • Short backoffs,

  • Delayed SL/TP placement (3 seconds) to exit freeze zone.

• Transparency — detailed logs and optional AI response saving.

How it works

1. Data collection: candles (M1…MN1), indicators, levels, balance/margin/positions.

2. Query formation: considers MaxRisk, instrument parameters (step/min lot, Stops/Freeze, margin), and news.

3. AI response: action, SL, TP, short explanation.

4. Execution: lot calculation → position open/adjustment (with StrictDirection) → SL/TP placement.
